Nordson EFD

The world's leading designer and manufacturer of precision dispensing systems that apply accurate, consistent amounts of the adhesives, sealants, lubricants and other assembly fluids used in virtually every manufacturing process.

Adhesives/Dispensing

Since 1963, Nordson EFD has helped thousands of companies achieve these benefits with benchtop dispensers for manual assembly processes, dispense valves for automated production lines, XYZ dispensing robots, and the highest quality dispensing tips, syringe barrels and other disposable components in the industry. EFD products also include high-quality solder pastes for improving productivity in surface mount and electromechanical manufacturing processes, and the unique MicroCoat® system, which is changing the way lubricants are applied in the metal stamping industry.

In 2000, EFD was acquired by the Nordson Corporation of Westlake, Ohio.

Sales and service are available in over 30 countries through a network of local EFD offices and authorized distributors.

Laser Solder Reflow: A Process Solution Part II

Sep 13, 2007 | John Vivari; EFD, Inc., Alex Kasman, Leister Technologies USA

With the use of laser light for reflow having been established, all that remains is to apply it to best effect. Each time a laser is fired, it pumps a specific amount of energy at a particular wavelength to a particular point in space. Where technique comes in is choosing where and for how long to apply that light along with the application of accessory equipment to optimize solder paste reflow. This presentation covers the specifics of how to determine which process choices are the right process choices based on the needs of your product to maximize yield and throughput....

Laser Solder Reflow: A Process Solution Part I

Sep 06, 2007 | John Vivari; EFD, Inc., Alex Kasman, Leister Technologies USA

EFD Inc. and Leister USA have collaborated to bust the myth that you cannot perform laser reflow with solder paste. Using Leister diode lasers, EFD has formulated solder pastes that survive the rapid reflow cycle typical of laser heating. These solder pastes reflow and wet well, without spatter, even when heating is accomplished in less than half a second. The flux core in wire solders cannot boast such flux spatter resistance in such an aggressive heating environment....

Reflow Profiling Guide

Air Powered Dispensing

Jan 31, 2007 | John Viviari, EFD, Inc.

Air-powered dispensing systems use controlled pulses of air pressure to dispense solder paste from syringe reservoirs in uniform amounts. In this paper, EFD explains the most critical variables affecting air-powered dispensing of solder pastes and shows how to manage those variables to your advantage....

Dispensing Solder Paste Micro-Deposits to 0.2mm - A Process Solution

Jan 03, 2007 | John Vivari / EFD Inc.

Solder paste dispensing is not a new process. However, today's microelectronics present a daunting array of technical challenges to meet deposit size requirements. The need for better paste formulations, more precise equipment, and more tightly controlled processes is driving paste suppliers and equipment suppliers to develop new methods and materials. The most challenging solder paste deposits are those smaller than 0.25mm in diameter and today’s electronics demand such deposits. This paper addresses the process requirements for solder paste micro-deposits in terms of material, equipment and process variable control required for success in producing 0.25mm and smaller deposits....

First Principles of Solder Reflow

Dec 18, 2006 | John Vivari / EFD Inc.

Many solder users have preconceived notions and worries involving reflow profiling guidelines. Year after year of reading profiling recommendations in industry publications, from a litany of pundits, has made it clear that perfect profiles exist and should be sought after. They feel if the solder supplier gives them a tidy drawing on a piece of paper with times and temperatures that it will magically solve all their reflow problems. This is, unfortunately, an often incorrect assumption....

Tombstone Troubleshooting

Oct 26, 2006 | Michael Forti, Applications/Process Engineer, EFD

There have been many studies of the causes of tombstoning; some published, some not. They tend to focus on a single process parameter as the root cause of tombstoning. However, there is no single process change that is a sure cure for tombstoning! Those that claim otherwise are either uninformed or trying to sell you something. Rather than limiting your view to a single solution, EFD recommends you heed all of the studies. Like pieces of a puzzle, each study does not reveal the whole picture, but looked at all together, the picture is clear....
